A well interconnected (and, for its age, very nice looking) stone/tech base. Progression is very non-linear and you can move around most of the map almost any way you want. There's enough action along the way to at least keep you interested but there are also a few problems. Much of the map is a little dark, which, along with some other details (such as having to backstep into teleporters to proceed), makes progression confusing sometimes. The exit switch doesn't work. Worth a look for nostalgics. --3/5
